It's annoying to guess at the brightness of an indicator when calculating for an LED.

Why I built an LED luminosity tuner

Things I've Built

AVR Programmer

This is a handy device that can be soldered directly to one of the original NANOs and turn them into dedicated programmers. I always have a handful around my programming area.

Lots of tiny Projects

Various creations

Wireless Model Rocket Launcher

This is an old project that has BT3.5 and has about 100 ft range. It's always fun to bring out. Runs on 2S 14650 which is enough to cause an immediate launch.

8 channel dimmer

8 Channel dimming circuit

CMOS Aircraft Light controller

Uses a CD4060 to decode and control blink patterns for Boeing and Airbus patterns. Did very well with hobby and RC folks.
